'CHARLES II. ANDERSON, OF IIUNTINGDON, PENNSYLVANIA.

BUCKLE.

SPECIFICATION forming part of Letters Patent N o. 393,736, dated December 4, 1888.

Application tiled April 3, 1888.

To all 'whom it may concern: o

Be it known that I, CHARLEs H. ANDERSON, a citizen of the United States, residing at Huntingdon, in the county of Huntingdon and State of Pennsylvania, have invented certain new and useful Improvements in Buckles; and I do declare the following to be `a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains| to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon,which form apart of this specification.

My invention relates to harness or st-rap buckles, and has for its object the secure engagement of the strap and convenient release of the same when desired.

To these ends my invention embodies certain features of construction, which will be hereinafter fully described in the specification, and then definitely indicated in the appended claims.

In the accompanying drawings, which illustrate my invention, Figure 1 is a perspective view of my improved buckle with strap shown locked. Fig. 2 is a longitudinal section on a plane passing through the locking-pin.' Fig. 3 is a perspective view of a m odiication. Fig. l shows another modification.

The buckle is providedwith a frame, 1, having lateral vertical wings, as shown. The fixed strap 11 maybe secured to the bottom of this trame, as shown in Figs. 1 and 2, or it may be secured to a metallic loop, 13, as shown in Figs. f3 and l. In the bottom of the frame is a slot, 9, the function of which will presently be set forth. Slots or guideways 2 2 are made in the side wings of the frame, which form bearings for the trunnions 3 of alock-piece, J., adapted to slide in the slots. The slots are inclined downwardly in the direction in which 'the strain will be exerted when the buckle is in use. As will be seen, when the free strap 12 is slipped into the frame, it' the lock-piece l be pushed forward it will be carried down into tric-tional engagement with the free strap by the inclined guideways. An arm, 5, is att-ached to the locking-piece. On the under face of the arm is a pin, 10, made of such a size that it will readily enter a hole in the strap. The arm 5 .is provided at its end with.

Serial No. 269,458. (No model.)

a spring-catch, 6, which co-operates with a bar, S, suitably secured to the frame.

The operation ot the formv shown in Figs. 1 and 2 will now be understood. The lockingpiece is slid back to the highest part of the guideways 2 2 and the free end of the strap 12 is inserted. Said strap is drawn as tight as desired, and pin 10 is inserted in one of its holes. The locking-piece is pushed forward tionally the strap 12. At the same time the catch 6 comes under the bar S and establishes a firm lock. To unbuckle the strap, the catch G is pressed down with the thumb and strap 12 pushed forward quickly, when arm 5 will iiy up and locking-piece 4 ride up on the guideways. This throws pin `10 out of the hole in the strap, and the latter may be withdrawn. The slot 9 in the bottom of the frame is preferably left open. Then the iixed strap is secured as shown in Figs. 1 and 2, a slot is cut in it to register with slot 9. Any dust or dirt sediment which may accumulate in slot 9 may thus be readily removed. In fact, it will not ordinarily accumulate, because it iinds a free exit. This opening may also be used to push out the pin 10 in case arm 5 should not readily rise on opening the buckle. The frame need not of necessity be made of an unbroken web of metal, as shown, but may be ot' a skeleton form, if desired, the only desideratum being that suitable bearingsurfaces under the path of the lock-piece4 and under bar S shall be provided.

In the modification shown in Fig. 3 the fixed strap 11 is secured to a metallic loop, 13, pivoted in the end of the frame 1. A gripping-bar, 14, is carried above the pivotal points, so that when the buckle is under strain this bar will be forced down into firm frictional engagement with strap 1 2.

In the modification shown in Fig. L the rear end of the frame is bent down at 13 to form a loop, to which the fixed strap may be secured.

Having thus described my invention, what I claim as new, and desire to secure by I.etters Patent, is-

1. In a buckle, the combination, with a frame to receive the strap, of a locking-piece sliding in guideways in said frame, the guide- Lways incliningtoward the face of the strap and rides down the gnideways and grips fricmid a spring-catch for locking,r the pieces in iirm engagement with the strap and preventing the pin from Slipping. t

3. In a harness-buckle, the combination of g :L frame, l, Said frame being provided with lateral slots or guideways 2 2, looking-piece 4, Sliding in said guideWayS, arm 5, pin l0, slot in the frame, eo-operm'ing iviih Said i pin, and a Spring-Catch for looking the :xrm l when in engaigemenY \vi1'h lthe Strap. i

4. In a harness-buckle, the combination of frame l, a locking-piece lcrunnioned in the sides 0f the frame, a pin on said piece adapted to enter a hole in the strap, a detent for leekng the pin in place, and a pivoted loop for attaching the 'ved strap, said loop being provided with a friction-grip for engaging the loose strap.

5. In a harness-buckle, the combination of frame, inclined guideways 2 2, and slot 9 in said frame, sliding locking-piece 4, trunnioned in the guideways, arm 5, spring-Catch 6, bar 8, co-opera'ting therewith, and pin 10, as and for the purpose described.

In testimony whereof I affix my sig-nature in presence of wo witnesses.
